Abstract (en)
[origin: WO0135054A1] In one example, an orientation dependent radiation source (122A, 122B) emanates radiation having at least one detectable property that varies as a function of a rotation of the orientation dependent radiation source (122A, 122B) and/or an observation distance from the orientation dependent radiation source (e.g., a distance between the source and a radiation detection device). In one example, an image metrology reference target (120) is provided that when placed in a scene of interest facilitates image analysis for various measurement purposes. Such a reference target (120) may include automatic detection means for facilitating an automatic detection of the reference target (120) in an image of the reference target (120) obtained by a camera, and bearing determination means for facilitating a determination of position and/or orientation of the reference target with respect to the camera. In one example, the bearing determination means of the reference target (120) includes one or more orientation dependent radiation sources (122A, 122B).
